SPECIFICATION forming part of Letters Patent No. 386,393, dated July 17,1888.

Application filed February I, 1888. Serial No. 263,225).

To all whom it may concern.-

Be it known that I, J .mrns M. FLACK, a citizen of the United States,residing at Shelby, in the county of Cleveland and State of NorthCarolina, have invented new and useful Improvements in Ghurns, of whichthe following is a specification.

This invention relates to those churns which are inclosed by awater-jacket containing a thermometer and provided at the top of thechurn-body with a water-inlet and at the bottom of said body with awatenoutlet, for the purpose of heating or cooling the milk by hot orcold water poured into the water jacket, the temperature of the milk inthe churn being indicated by the thermometer.

The objects of my invention are to simplify the construction and reducethe cost of manufacture, to provide a novel structure for the purposementioned, and to avoid inclosing the entire churubodyin a water-jacket,and thereby reduce the bulk of the churn. These objects I accomplish bythe novel construction of parts, hereinafter described and claimed,reference being made to the accompanying drawings, in which Figure 1 isa eertral vertical section taken in the line of the axis of the churn,illustrating my invention; and. Fig. 2 is a front elevation of the same.

In the said drawings, the reference-numeral 1 designates the body of thechurn, which is of any suitable form and material.

The numeral 2 indicates a chamber semicircular in crosssection andextending horizontally around the churn-body as a closed trough. Thisannular chamber or closed trough has two closed ends, 5, arrangeddirectly opposite each other and separated by an intervening verticalchannel or space, 6, one of said end portions carrying on its upper sidea lip-funnel, 3, and the opposite end portion carrying on its lower sidean outlet pipe or nozzle,4. The chamber 2 is formed of a strip of metalbent into semicircular form transversely from end to end, and itslongitudinal edges are soldered to the externalsurface of the verticalwall of the ehurubody entirely around the same, except as to theintervening space between the closed ends 5, hereinbefore men- (Nomodel.)

tioned. This construction provides ample means for holdingthe hot orcold water, while it can be applied to any metal churirbody,and it is byfar less bulky, more simple, and much less expensive than a water-jacketentirely surrounding the sides and bottom of a churn body.

The walls of the churn-body or vessel being metal, 1 find that theannular semicircular chamber 2, constructed and applied horizontally tothe body about midway between the top and bottom of the latter, meetsall conditions required, as the metal of theehurn-body conducts heat orcold from the liquid in the chamber to the milk. A thermometer, 7, isarranged in the vertical channel or space 6 between the opposite closedends of the annular chamber, and has direct contact with the surface ofthe churn-body, for indicating the contents of the churn by the usualthermometric column. By this construction I avoid recessing and cuttingaway the metal of the water-chamber to place a thermometer against thechurn-body. By means of the chamber 2, composed of the metal bent asdescribed and soldered along its horizontal edges to the externalsurface of the churn-body, I provide an annular troughlike receptacle,by which a continuous stream of water may be caused to pass around thechurn in a horizontal line, the stream entering at theinlet-lip funnel 3and escaping at the outlet-nozzle 4, and by passing hot or cold waterthrough such trough the temperature of the contents of the churn may beraised or lowered accordingly. The chanr her or trough is entirelyclosed at the top and bottom, except of course as to the inlet andoutlet.

I do not broadly claim a water-jacket about a milk or similar vesselhaving an inlet and an outlet, as in Letters Patent Nos. 168,123 and137,369, as such of itself is not new with me.

hat I claim is- A metallic churirbody having the semicircular closedtrough 2, provided with closed ends and extending horizontally around itand composed of a strip of metal bent transversely into semicircularform and soldered along its upper and lower horizontal edges to theverdirectly on its lower side an outlet, substanits top and bottom, saidclosed ends of the tially as shown and described. IO trough beingarranged directly opposite each In testimony whereof I affix mysignature in other and separated by an intervening chanpresence of twowitnesses.
